Setting imexpire Rules Textually

Automatic message removal rules are set by specifying rules in a store.expirerule file. The store.expirerule file contains one expire criteria per line. An expire criteria of the global rule configuration file (msg-svr-base/data/store/store.expirerule) has the following format:

rule_name.attribute: value

An expiration rule for a user or mailbox rule configuration file has this format:

attribute: value

Example 20–4 shows a set of global expiration rules in msg-svr-base/config/store.expirerule.

Rule 1 sets the global expiration policy (that is, policy that applies to all messages), as follows:

• Enable UNIX regular expressions in rules creation.

• Removes messages larger than 100,000 bytes after 3 days.

• Removes messages deleted by the user.

• Removes any message with the strings “Vigara Now!” or “XXX Porn!” in the Subject: header.

• Limits all folders to 1,000 messages. After 1,000 messages, the system removes the oldest messages on a folder to keep the total to 1,000.

• Removes all messages older than 365 days.

Rule 2 sets the automatic message removal policy for users at the hosted domain siroe.com. It limits mailbox sizes to 1 megabyte, removes messages that have been deleted, and removes messages older than 14 days.

Rule 3 sets the automatic message removal policy for messages in the inbox folder of user f.dostoevski. It removes messages with a subject line having the expression “On-line Casino.”
